Unable to mount large external disk on Centos 7 #108

Open mbach04 opened 5 years ago

[root@localhost ~]# mount.exfat-fuse -o ro /dev/sda /mnt
FUSE exfat 1.3.0
WARN: file system in sectors is larger than device: 250083328 * 512 > 127865454592.
ERROR: file system in clusters is larger than device: 976848 * 131072 > 127865454592.

Is there some means to bypass this warning and mount anyways? I understand the disk is much larger than the file system, but I'd still like to mount and read a file etc.

I'm also seeing an issue with unmount on a much smaller drive using the same version of exfat-fuse that causes the tty to hang completely. The session freezes completely.

Only by editing the source code. This check is here because of some buggy embedded implementations (e.g. in cameras).

Please file a separate issues with more details.

Yeah, prior to the issue submission I had done just that. I guess I was thinking if this is something that only affects a small handful of devices, then it would be best to have an option to ignore it, log the error to stderr and move forward with the mount.
